Research Engineer | Bioprinting & Lab Instrumentation

About

Ozer Yilmaz is a research engineer at the Ozbolat Bioprinting Lab at Penn State and a PhD candidate at Istanbul Technical University. His work sits where biology meets machine design: extrusion and droplet bioprinting, microfluidics, and 3D in vitro tissue models, together with the custom hardware and software those experiments run on.

He designs printheads that change shape mid extrusion, builds browser based control software for laboratory instruments, and writes the analysis pipelines that turn raw scans into measurements. He holds an M.Sc. in Biotechnology and Bioengineering from the University of Kent and a B.Eng. in Chemical Engineering from Marmara University, and has authored nine peer reviewed publications, two as co-first author.

Welcome to my digital space

I build the machines that biology gets printed with, and the software that runs them. Most of my week goes to pressure lines, stepper motors, cell culture, and code that has to keep working overnight. This page is where I keep notes on that: what I am building, what broke, and what it taught me.

About me

Born in Turkey, trained as a chemical engineer, now working on bioprinting hardware.
Living in State College, PA. Outside the lab, mostly hiking.

I believe in...

  • A small tool built in an afternoon is often worth more than a workflow everyone puts up with
  • A protocol is finished when someone else can run it and get the same result
  • Lab software should open in a browser, with nothing to install
  • Building the hardware surfaces problems that simulation does not

Lab Tools

Lab tools I built as single HTML files. Nothing to install and no account needed, they run in the browser.

  • OZ Bioprinter// /bioprinter Control interface for the extrusion bioprinter over Web Serial. Jog the axes, run pressure on both printheads, send G-code straight from the browser.
  • OZ Droplet Printer Studio// /droplet Pattern and dispense planning for the Jetlab4 piezoelectric inkjet printer, with waveform and array setup.
  • OZ Robot Studio// /robot Path planning and SPEL+ code generation for a six axis EPSON C8 arm. Lay out the motion, export the program.
  • G-code to STL// /gcode2stl Converts a G-code path into an STL mesh, with a 3D viewer to check the result before printing.

Currently exploring...

  • A printhead that changes its own cross section mid print, six bladders on a pneumatic rail // SHAPE_SHIFTING_NOZZLE // IN_PROGRESS //
  • Raw optical coherence scans turned into corrected organoid volumes // OCT_PIPELINE // IN_PROGRESS //
  • Printing a whole construct in one rotation instead of layer by layer // CAL_VOLUMETRIC // PLANNING //
  • A round display with cartoon robot eyes that blink while experiments run // DESK_BUDDY // HIBERNATING //
